The idol stars joined Soyu on an indoor surfing trip, where they learned how to surfboard. However, Soyu and Kihyun couldn't stop bickering throughout the entire show, just like real siblings!
Before jumping into the water, the trio chatted about their favorite cosmetic items, such as, 'fixing mist' and 'makeup sealer'. Just when Soyu was about to spray some mist on Kihyun's face, he blurted, "I already sprayed my face beforehand." Soyu then barked back, "What is the most important thing to remember when putting on mist?"
Kihyun responded, "Spray within 30cm," but Soyu refuted, "It's 15cm. You learned wrong. It's like you gotta start over from the beginning."
